Note: This is my own personal experience with this company, and not necessarily indicative of their general operations. You can choose to believe it or not believe it. I have not made a complaint to ACCC despite being entitled to act on their misleading and deceptive conduct because I don't think it's worth my time and the amounts of money involved are small.
I wanted my room and the hallway outside my room steam cleaned. I did a Google search and found CheapAsChips. After calling the number, the guy said it could be done for $66. They also advertise on the internet saying they can do 3 rooms for $66, so one room and a hallway seemed within that range.
When their man showed up, he asked me to help him carry his equipment into the house. I thought that was a bit unprofessional and rude, as I paid for a service not to help him. He also looked at the carpet and decided that it would have to be more expensive: $99 for a room and hallway. I replied that this was not what I had been quoted on the phone. He responded that the guy on the phone hadn't seen the state of the carpet which was apparently dirtier than normal.
Because I had already taken time out of my day to travel to my new rental house, and the guy had already showed up, I didn't want to reject him completely especially as I was moving in a few days into the new place. So I agreed if he could do one room for $70 that'd be fine.
However I am warning anyone else not to trust this company as they could have told me on the phone that their quote was not a genuine quote, but dependent on the state of the carpet. My carpet was probably only slightly more dirty than an average carpet (it was a bit old, that is true). I was not told about the quote being only indicative and not a genuine quote until the last minute. They should have informed me of all the details prior to me wasting time booking them.
And finally, the company's actual cleaning of the carpet was pretty average and a quick 10 minute job. It would've been nice for their man to vacuum the carpet before wetting it.
